Antioxidation anticorrosion transformer oil containing multiple nanoparticles and preparation method thereof

Abstract

Disclosed antioxidation anticorrosion transformer oil containing multiple nanoparticles is characterized by being prepared from the following raw materials in parts by weight: 1000-1500 parts of cycloalkyl base oil, 2-4 parts of aluminium nitride, 0.2-0.5 parts of molybdenum disulfide, 0.3-0.5 parts of polyisobutylene, 0.5-1.0 parts of active alumina micro powder, 0.2-0.5 parts of resorcinol, 0.2-0.5 parts of nanometer tantalum carbide powder, 0.2-0.5 parts of butylated hydroxytoluene, 2-4 parts of boron phosphide, and 0.5-1.0 parts of an auxiliary agent. The nanoparticles are prepared by utilizing an absolute-ethanol ball milling method, and employed equipment is simple and easy to operate. The added multiple nanoparticles help the transformer oil to improve insulating property and heat conduction property and enable the dielectric coefficient to be small. The added auxiliary agent improves the anti-oxidation, anti-corrosion and insulating properties of the transformer oil. The problems that transformer oil is easy to oxidize and corrode, is not long in service life and the like are effectively solved, and the safety coefficient of the transformer oil is substantially improved.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to an anti-oxidation and corrosion transformer oil containing various nanoparticles and a preparation method thereof. Background technique [0002] Many high-voltage equipment today use transformer oil as the insulating cooling medium. Transformer oil has a much higher dielectric strength than air. Immersing insulating materials in oil can not only improve the insulation strength, but also prevent moisture erosion. The heat generated during the operation of the transformer causes the oil close to the iron core and winding to expand and rise. Through the convection of the oil up and down, the heat is dissipated through the radiator to ensure the normal operation of the transformer. On oil circuit breakers and on-load tap taps for transformers, arcing occurs when the contacts switch. Due to the good thermal conductivity of transformer oil, and under the high temperature of the arc, it can to...

Problems solved by technology

After deep oxidation of oil products, oil sludge will be produced. After the oil sludge is precipitated, it will be deposited on the surface of the iron core and coil, causing poor heat transfer and temperature rise of the solid insulating layer, aging and cracking the solid insulating material, and seriously threatening the long-term operation of the transformer.
